视场

Clicking on this button will recompute the vignetting factors for each field based upon the current lens data.

点击键将根据当前镜头数据重新计算每视场的渐晕因子。

Many parameters are required to describe their performance, which is transmission ratio, extinctivity ratio, angle of view field, splitting angle, etc.

激光偏光棱镜技术参数较多，透射比、消光比、视场角、分束角、长度孔径比等。

This paper introduced the Method of Dark-field Illumination to develop poroscopy on the glass, and some factors related to forming of poroscopy were also studied.

文章采用一种用的配光方法―暗视场照方法，显现光滑平面玻璃上汗潜指印的汗孔细节特征，并对实验中影响汗孔细节特征形成的部分因素进行了初步研。
